I'll post the log later but peak boost was ~20.5psi and we're running around 13 degrees peak advance on it. Overall car performed very well and we were happy to raise the bar on stock turbo performance a bit.

Attached is the dyno sheet and a photo of the car & Jon working the dyno software.

I hit 469 hp and 491 tq on stock turbos a few weeks ago on map 6 with garth at Undercover tuning. I will see if he can send me that pull. FBO+100% e85 with BMS Flash. Did not realize the stock turbo HP record was mine , that was with a failing HPFP that kept falling on its face in the midrange but recovering up top. @undercoverangie can you ask garth to dig up the dyno graphs and send the 469/491 pull to me so I can post it.

Damn, how "safe" is 21psi midrange on stockers??? And I thought 19 was too aggressive

Safe is a relative term. The turbos already smoke a bit on the car and will be replaced at some point in the near future. So from that perspective I don't have any issues with it. From an engine safety standpoint this is a lot of boost for the fuel being used. If doing runway runs for example I'd probably tone it down to 19psi peak. Which was around 440rw.

This is also on a DynoJet that reads WAY higher then our dyno... requested that Garth finds your pulls.. he is very intrigued by this

For dyno records you normally need to use a dynojet due to how standardized they are. Load dynos can be all over the place depending on settings, correction factors used, etc. But I have a feeling both cars are in the same ballpark since they are using the same tuning.

Would 21psi be okay on straight E85?? Or is that still too much boost to run on the stock turbos + expect them to last?

It's just an excersize in tuning. This run was done using all off the shelf stuff. Our canned backend flash, JB4 map 3 using an 85 additive iirc, etc. To try to achieve this without meth would require some work on the flash and fuel system side but should be doable. I'd start by getting map 7 going, which is 18.5psi peak. That should get you in the 440rw range. From there you'd have to add boost as fueling allowed. This same car did around 448rw on E85 only at around 20psi iirc.

The turbos won't last like that but are cheap to replace. The bigger risk would be engine damage if it was not tuned up properly and you were doing long runway runs with it.

Hey I still have a few gallons of FTWE85 to throw in when someone passes us up.

Photo is Jon @ BMS. We both took sabbaticals from our male underwear modeling careers to start BMS.

haha... FTW baby... I'm afraid to put that stuff back in my car... I still have what I pumped out of my tank on Sunday at SS... Hopefully I'll have all the bugs worked out of my car next week. Already had one dealership kick me out the door and told me never to bring my car back to them because they found a few things. Didn't pull my Alpina flash and they flagged it in diag along with a few other things. Lucky for me the SA was a friend of a friend and they didn't send anything up to BMW. So I'm going on Monday to have my normal dealership replace my injectors and fix anything else they find wrong. Probably should have taken it to them anyway, but it was a dry run to see what they would find. So she's back to 100% stock now and hopefully they don't have any issue doing the certification for turbo replacement. Hopefully my car won't smoke anymore. LOL If not, I'll have to find a dealership that will. Road trip...

(I'm a bit spooked on the FTW myself... We put some in the N55 and it seemed fine but a day or two later it's misfiring randomly. Coincidence? Not sure... But I won't be running the stuff anymore unless absolutely necessary. e.g. if the car does 11.001 or something)
